Vehicular communication, also known as vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I), is an emerging technology that allows vehicles to communicate with each other and with the surrounding infrastructure to improve traffic safety, efficiency, and flexibility.


Vehicular communication uses a variety of wireless technologies, including Wi-Fi, Bluetooth, cellular 5G and dedicated short-range communication (DSRC), to exchange information between vehicles and with supporting infrastructures, such as road signs, traffic lights and navigation systems.

One of the main functions of vehicular communication is vehicle cooperation, which allows vehicles to share information about location, speed, direction, and other characteristics in order to avoid accidents, reduce traffic, and improve transportation efficiency. For example, vehicles can warn other vehicles about an incident or a construction zone, allowing them to slow down or change their route in a timely manner.

Additionally, vehicular communication can also be used to integrate vehicles with navigation systems, signaling systems and traffic management systems, allowing them to follow optimal routes, avoid congested areas, and adapt to real-time traffic conditions.

Vehicular communication is also an important component for autonomous driving, as it allows vehicles to communicate with each other and with the infrastructure to create a precise map of traffic conditions and to avoid accidents.


Currently, vehicular communication is under development and implementation worldwide, with many governments and companies investing in this technology to improve traffic safety and efficiency. However, there are still some challenges to overcome, such as data security, interoperability between systems, and the need to standardize technologies and procedures.

In general, vehicular communication represents an important step towards a safer and more efficient future for transportation.
